Application filed November 11, 1919. Serial No. 337,309.

To all whom it may concern:

Be it known that I, JOHN P. Roman, a citizen of the United States, residing at Knoxville, county of Knox, State of Tennessee, have invented an Improvement in Filling Clamping and Parting Mechanism for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing,representing like parts.

This invention relatesto automatic filling replenishing looms wherein the running filling is replenished prior to complete exhaustion and wherein the old or spent filling is parted between the cloth and the shut tle by partingmeans mounted upon the carrier such as the usual swinging shuttle feeler so as to be moved bodily rearwardly and forwardly or toward and from the lay.

The object of the invention is to provide an improved, simple, and effective means for operating the filling, clamping and parting means when, and only when, a fresh filling carrier is transferred from the hopper or supply to the shuttle 0n the lay.

The invention is an improvement upon, and is similar in its general object and purpose to that shown in, the patent to Davis No. 1,084,557 8 granted January 20, 1914.

The nature and object of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claim.

The drawings illustrate the invention as embodied in the well known Northrop type of automatic filling replenishing looms.

In the drawings- Figure 1 is a transverse section of a portion of the automatic filling replenishing loom with the present invention embodied therein.

Fig. 2 is a detail in front elevation of the upper portion of the carrier for the filling clamping and parting means and the parts connected thereto.

The construction and operation of the automatic filling replenishing loom herein illustrated being well known and familiar to those skilled in the art, and the patent to Davis above mentioned showing a construction securing the same broad result as that here secured, it will be necessary to describe in detail only those features and their operation immediately concerned with the present invention.

The loom frame 1 supports the hopper 2 containing the supply of fresh filling carriers lVhen the running filling in the shuttle on the lay has become substantially exhausted, indication of that fact is trans mitted through a well known mechanism to the rod 4 which is thereupon rocked to raise the arm 5 and swing the shuttle feeler 6 rearwardly and at the same time to raise the dog .7 connected to the transferrer 8 into'the path of a'bunter 9 on the lay 10. If the shuttle is properly boxed allowing the shut tle feeler to pass the end of the shuttle, then the hunter 9 striking the dog 7"swings the transferrer 8 downwardly, forcing a fresh filling carrier3 from its position in the hopper down into the shuttle 11 on the lay 'therebeneath, and simultaneously ejects the partially spent shuttle therefrom. When the fresh filling carrier is in the hopper ready for transfer it rests against an abutment 12 and over a support 13 pivoted at 14 so that in order to pass out from the hopper into the shuttle this support 13, must be swung downwardly about its pivot. This support has rigidly connected with it a fin ger 15. A spring 16 is held between a notched or slotted lug 17 projecting from the hopper stand Qand the head 18 of a slide rod 19 connected with the finger15, and. thus acts to hold the pivoted support 13 in, and return it to, its normal posit1on as illustrated in Fig. 1.

The shuttle feeler 6 acts as a carrier for the filling clamping and parting means -filling replenishment the shuttle feeler 6 swings rearwardly, the movable blade is swung upwardly at its rearward end and in this position the filling clamping and part- 7 into contact with the lower camsurface of' ing means pass overthe filling extending from the spent shuttle to the cloth The movable blade is then swung downwardly parting and clamping the filling and then when the shuttle feeler swings forwardly the clamped end of the filling is carried for-; wardly so as to bring the filling into the path of the usual temple'thread cutter." The movable blade" is opened when the shuttle feeler swings rearwardly by a pin 23 projecting laterally therefrom coming a catch 24: pivotally mounted at 25 uponan upstanding bracket 26; This catch swings freely forwardly to allow the pin to pass when the shuttle feeler swings to forward position.

c u such a manner that this closing movement The present invention is particularly concerned with the means for efiecting the clos r ing movement of thelmovable blade 20in shall not take place unless the fresh filling carrier is actually transferredfromthe hopper to the'shuttle on the my; It sometimes happensthat this transfer is not effected and i if the movable blade should be actuated under these circumstances therunning filling V i would be severed and the shuttle would then piece of stiff wire coiled at one end about make two picks vwithout laying filling and thus produce an imperfection in the goods.

In this invention the closing operation of "the movable blade 20is efi'ected by or through the movement of the filling carrier support 13. A bracket 27 is rigidly secured to and projects upwardly from the shuttle" feeler 6. This bracket is extended rearwardly parallel i with the head of the shuttle feeler to form a shaft or stud 28, and on thisstud is pivotally mounted or fulcrumed a lever. This lever is conveniently made of a single pieceof stiff wire. The central portion is wound in spiral form to form the hub 29 while one end forms an arm 30 extending laterally toward the hopper and theiother end forms an arm 31 l extending in the opposite direction. "The hub 29 is held' in place between a collar 32' V andawasher 33 secured by a'cotter pin 3 on the stud'QS. The arm 31' is secured by a rigid link 35 to the pin'23. To allow the re quired movement thislink is made of a 'arm 31.

the pin 23 and at the other. end coiled about and engaging a hook shaped bendinthe i The finger 15 connected with'the filling carrier support 13 is provided with anarm 36, secured to and projecting iforwardly therefrom. The arrangement'of the parts is such that when the shuttle feeler with the filling clamping and parting means is moved 'rearwardly into position to clamp andipart the filling thearm 30 will be directly beneath the arm 36. Consequently when the transferrer 8 swings downwardly and 'a filling carrier is present beneath the transferrer the filling carrier support 13 will be rocked downwardly carrying with' it the arm 36 thus depressing the arm 30 raising the arm pressits rearward end to clamp and part the filling. V

. Thus a simple 7 31 and rocking the movable blade 20'to deandeffective means is pro- 1 vided by which the movable blade is actu- 7 I ated to clamp and part the filling only when an actual transfer of a fresh filling carrier is made from the hopper to the shuttle.

Having thus described my invention what i I claim as new and desire to secure'by Letters Patent is c i An automatic filling replenishing loom comprising a hopper for the fresh filling carriers, a filling carrier support movable to,

release a fresh filling carrier from the hopper an arm secured to and projecting forwardly from said support, filling clamping and parting means including a pivotally mounted member acting whenits rearward end is depressed to clampand part the filling, a rearwardly and forwardly movable carrier for the clamping and parting means, a bracket mounted on .the movable carrier, a lever pivotallyinounted on the bracket and having one arm extending beneath the arm JOHN P.
